• particles in an object have less energy
• particles in an object move faster
• a gas contracts

What causes a change to state of matter when thermal energy is increased?

• Bonds between the molecules break and the molecules separate

• Bonds between the molecules form and the molecules get closer together

• The molecular bonds stay the same

• The molecules undergo a chemical reaction and change into new molecules

Particles vibrate in place and do not change relative positions.

• solid

• liquid

• gas

What is Matter? 

• Tiny particles that make up matter
• Anything that has mass and takes up space-Solid, Liquid,and Gas
• Particle that is made up of multiple types of atoms bonded together
• Material made up of shapes
